What does 1 megajoule represent?

One megajoule is an SI derived unit of energy equal to one million joules, commonly used to measure transferred or stored energy such as work, heat, or chemical energy.

What is a kilowatt-second used for?

A kilowatt-second equals one kilowatt of power delivered for one second and is used to express short energy pulses in areas like power electronics and transient events.

How do I convert megajoules to kilowatt-seconds?

Simply multiply the value in megajoules by 1000 to get the equivalent energy in kilowatt-seconds, since 1 MJ equals 1000 kW*s.
